Thanks for respond, @Amy Masse. You're rigth. And my clients uses it as asymetrical (non-miror) drill.But after update from 8version to 10.3 we found next. When we open mirror piece in PDS the dril/line labeled E is mirror. We was shocked and afraid for made database: model and markers.Later i'd check it in marker. So there is allrigth in marker - E not mirror, but in PDS - E is mirror.
